RSNetWorx for ControlNet Configuration
See the RSNetWorx for ControlNet Getting Results Guide, publication CNET-

Follow these steps to configure the ControlNet network.
1. Launch RSNetWorx™ for ControlNet and create a file.
2. Click the Online button.
The Browse for Network window appears with the drivers you have

IMPORTANT The recommended RPI is 1/2 the macrocycle time. Calculate the macrocycle by
calculating the total response time of all field devices on the segment and then
add 100
… 200 ms for class 2 (DTM message) data. If the RPI is too low, class 1
data (PVs and status) does not update each cycle, and class 2 data responses
can be slow.
